Wifi vs ethernet revisited

For this discussion I want us to forget the usual problems of wifi: stuttering, buffering, loss of signal strength. Let’s assume we have a strong, reliable wireless connection. Questions: how would you rank the following:

1. [No wireless, my current config] Ethernet from router -> Switch (or OM) -> fiber -> Etherregen -> ethernet -> streamer.

2. Eero wireless mesh -> receiver -> ethernet -> streamer.

3. Eero Wireless mesh -> receiver -> ethernet -> Etherregen -> ethernet -> streamer.

Or, to really go hybrid and (probably nuts):

4. Eero wireless mesh -> receiver -> ethernet -> Switch (or OM) -> fiber -> Etherregen -> ethernet -> streamer.

I haven’t done [4] yet. But to my ears, [1] definitely beats {2] and (less emphatically maybe) beats [3] even though I have a very strong Eero wireless mesh system. Maybe my assumptions to begin with are still wrong? I can’t seem to read a good forum thread where the usual stuttering’/buffering problems (that we all know about) are removed. Thanks in advance everyone!
